Serum is usually collected in mottled red/gray, gold, or cherry red-top tubes, and red-top tubes are occasionally used. Although there are two reports on the effect of recentrifugation on serum potassium concentration [1, 2], to the best of our knowledge there are no other studies to show the impact of re-centrifugation on the concentrations of multiple analytes that are routinely measured as part of "metabolic panel". Stability of common biochemical analytes in serum gel tubes subjected to various storage temperatures and times pre-centrifugation. Serum should be removed from the clotted blood as soon as possible after a red-top tube or serum separator tube (SST). Re: Why would a blood sample turn pink with centrifugation?

This is the supernatant that is removed after a clot has formed and centrifugation of blood collected in a red top tube (see note #3 below about serum separator tubes). A specimen collected in a blood collection tube with clot activator should be inverted five times to facilitate the clotting process. The physical force from continuous revolutions pushes the denser, heavier particles to the outer edges of the sample resulting in three layers of different densities: RBCs, a mixture of WBCs and platelets, and plasma. Separated cell-free serum or plasma is ready for testing. determination of lactate dehydrogenase) as the anticoagulants in plasma can sometimes interfere with the results. Serum is the liquid that is left over when the red blood cells and the clotting elements have been removed from your blood plasma.

Or higher serum does not need to be used add 2 ml red serum after centrifugation normal saline to the,. Serum provides the liquid portion of the blood without cells and clotting factors and, therefore, should contain proteins and other molecules that represent the whole body system. The upper layer which is obtained is serum, and the layer which got settled at the bottom is the clotted blood. Hemolyzed or grossly lipemic samples. Notice how the gel starts out at the bottom of the tube before centrifugation. serum group i.e. Grossly lipemic specimens should be cleared by ultracentrifugation. When you go to the doctor and they collect your blood, sometimes they spin down your blood to separate it into 3 different parts or layers that they can test for various things. This volume not only discusses various common biobanking topics, it also delves into less-discussed subjects such as what is needed to start a biobank, training of new biobanking personnel, and ethnic representation in biospecimen research.
